The essential oil obtained by hydrodistillation of the aerial flowering parts of Pulsatilla albana (Stev.) Bercht. & Presl. was analyzed by GC and GC/MS. Twenty-five compounds representing 97.5% of oil were identified, among them pulegone (39.1%), piperitenone (17.2%), menthone (16.1%), 1, 8-cineole (8.9%) and p-mentha-3,8-diene (4.2%). In this essential oil oxygenated monoterpenes (87.9%) predominated over monoterpene hydrocarbons (8.3%) and sesquiterpenes (1.3%). Nonterpene hydrocarbons were not found among the identified components. Antibacterial screening of the oil showed moderate activity against certain strains of Gram-positive and Gram-negative bacteria.
对白头翁（Pulsatilla albana (Stev.) Bercht. & Presl.）地上开花部分经水蒸馏得到的精油进行了气相色谱（GC）和气相色谱-质谱联用（GC/MS）分析。鉴定出了占精油97.5%的25种化合物，其中长叶薄荷酮（39.1%）、胡椒酮（17.2%）、薄荷酮（16.1%）、1,8-桉叶素（8.9%）和对薄荷-3,8-二烯（4.2%）。在这种精油中，氧化单萜（87.9%）的含量高于单萜烃（8.3%）和倍半萜（1.3%）。在已鉴定的成分中未发现非萜烃。该精油的抗菌筛选显示对某些革兰氏阳性菌和革兰氏阴性菌菌株具有中等活性。
